The intake check valve 66 being closed at this time, lubricant will be 'forcibly injected into 'the fitting. Upon the return movement, the spring 72 Will move the piston down again, the discharge check valve will close, and the intake cheek valve 66 Will open to permit the cylinder 62 to fill again With lubricant.

The inlet tube 48 is axially bored down to a transverse bore at 74, (see Figure 4) A pavvl, comprising a stem 76 and ahead 78, isslidably mounted in a suitable transverse bore in the tube 48 and urged radially outward by a coil spring 80, to engage ratchet teeth 82 on the inner periphery of the drive ring 44. To maintain communication between the inside of the drive ring and the chamber 30 surrounding the same, the drive ring is provided with a transverse notch at 84. A torsion spring 86, anchored at 88 in a. shallow annulus 90 in the body 24 and entering a transverse bore 92 at its other end, normally keeps the tube 48 in a predetermined position, limited by engagen'lent oit' a stop pin 94 With oneAsi de of a pocket 96 formed in the inner face. oi the cover 26.

ln operation, the torque necessary to ject lubricant Will rotate the inlet tube 48, through the displacement aerniitted by the pin 94, and further rotation of the compressor sleeve 62 will then inject lubricant. 0n the return stroke the turning torce on the tube 48 will be removed and the spring 86 Will return the parts to initial position. rlhis rotary reciprocation of the tube will reciprocate the paivl 78 to move the drive ring 44 in step by step movement and rotate the distributing means comprising the drive rin and the plates 40. Each di ibuting plate 40 is provided with an arcuate slot 98, and the plates are duplicates. The length of the slots 98 is such that as one slot nimy avvay from an outlet opening in the body, the. slot in the other plate will simultaneously uncover an outlet in the head. ln this way all the outlets are connected, one after another, to the chamber, but no two outlets are open at the same time, and there is `no appreciable interval when the chamber 30 has ne outlet.

Referring now to the showing of Figures 9 to 13, inclusive, I have illustrated a liront axle 11G carrying Wheels 1.12 on knuckles pivoted at 114, the axle beine" connected to the vehicle by springs 116iastened thereto by clips 118. The web of the axle is drilledat 120 to receive the fastening bolt 122 for fastening a body 124 in place, The body 124 terminates in a cup shaped head Lto-operating "with a cover 126, tasten-ed in place by bolts 128 to define a chamber 136. The outlet openings 132 are enlarged at 12,4 to receive the terminals 136 of plurality of small individual lubricant conduits 138 leading to the various elements to be lubricated. The distributor plates 140 are pivoted on a single central pin 142, received in the alined pockets 144 in the body and cover, and resiliently held in contact with the sides oit the chamber by a compression spring 146 encircling the pin.

The inlet tube 148 is slidable in a bore 150 in the body and provided With a suitable packing at lt is designed to co-operate with the type ol lubricant compressor operated by pressing the compressor against the inlet, such as that illus rated and described in co-pendingI application Serial No. 726,554, filed July 17, 1924, by Osc-ar U. Zerk. Such a compressor comprises, briefly, a. barrel 154 provided with an extension 156 supporting an end piece 158 in which a discharge tube 160 is slidably mounted. The spring 162 normally presses the tube 160 outwardly to the position shown in Figure 11, but an axial thrust against the receiving terminal 164 will slide the sleeve up over a stationary plunger 166. After theplunger passes the ports 168, the lubricant trapped in the sleeve 160 Will he 'forcibly ejected past a ball valve 179. The axial thrust is developed by force exerted on a handle 172 ri gid with a tubular piston rod 174, terminating in a piston 17 6, and after the pump is empty it may be relilled through the hollow handle 17 2 and the piston rod 174 by injecting iresh supply of lubricant past al check valve 178.

Under the axial thrust of the gun the inlet tube 148 Will slide in against the force of compression spring until the cylindrical end 182 abuts the far side of chamber 130. This movement accomplishes tivo things.

First, a yoke 184 straddling the member 148 and constrained to move axially there- With by engagement ot its sides in suitable notches in the sides of the inlet tube, engages ratchet teeth 186 formed on the outer periphery et each distributor plate 140 and rotates the distributor plates one notch dining the in stroke. @n the out stroke the yoke Will compress its holding spring 188 suiliciently to slip over 'the next tooth oit' the ratchet. ln this Way the step by step movement of the plates will bring the apertures 187 successively into register with the outlets 132 precisely as in the embodiment of Figure 2.

Second, the axial movement of the inlet tube carries a port 190 past the end of a boss 192 establishing communication with the chamber 180 so that injection of lubricant can occur. On the return stroke the seal is again formed at this point, and no other check valve means is necessary.

ldlithout further elaboration the foregoing will so fully explain the gist of my invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service. lt Will, for instance, be obvious that taking the conduits as-ana .ies-nem bou-1'sides-ofthechambers instead of one, notonly facilitates a compact l and' convenient arrangementof the Zconduits to" lead directlyfto the 1variousparts to be lubricated, butV substantially. doubles; the" numf ber of outlets that can be yproizided -i'fdesired to, injection meansoperate'd 'in one direction step by istep vact'ruati'on ofjsaid distributor Thus, While only threelivoutlets; in'V ,eachA side have 'been show-n, thernfiurrberfcan be fincreasedu-p vto fa Ilimit set by the y number of,
